Abstract:

A total of 1523 anthophilous Cerambycidae in Washington County, Ohio, were recorded over four field seasons (1995–1998) and included 22 genera and 28 species. The most commonly used inflorescenses were those of goatsbeard (Aruncus dioicus [Walt.]) and wild hydrangea (Hydrangea arborescens L.) in June through mid-July and Queen Anne's lace (Daucus carota L.) in late July. Judolia cordifera, Metacmaeops vittata, Strangalepta abbreviate, and two species of Brachyleptura preferentially feed upon goatsbeard and wild hydrangea. For the seven most abundant beetle species, there is a positive correlation between the number of plant species used and both the number of individuals of lepturine species and the length of their activity period, indicating that species which are common or have long seasonal phenologies use blossoms of many different plant species. At the most diverse site (Reas Run), the greatest number of species (16) was recorded in the third week of June, while the greatest number of individuals (118, although only two species) was observed during a week in mid-July. The most abundant species was Typocerus velutinus, accounting for 31 % of the observations. Analeptura lineola, Strangalepta abbreviate, and two species of Brachyleptura accounted for an additional 49.5% of the observations. The average length of adult activity on flowers (in species where a minimum of 10 individuals were collected) is 5.2 weeks, and the average number of plant species used is 9.38 with a maximum of 16 for T. velutinus.
